Perhaps you should try some spelling variations:
thai cua » than cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
cac xuc » cam xuc, cac nuoc, chat xuc
nang xa » nang x, lang xa, mang xa
nang ma » tang ma, sang ma, nang cao
ban ky » van ky, dan ky
va dan » ca dan, va dau, va dap
va dao » ca dao
tu ban » thu ban, te ban

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu ban ky ((nang xa) OR (nang ma)) hoi. lieu va cac xuc ((va dan) OR (va dao)) thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ban ky ((nang xa) or (nang ma)) hoi. lieu va cac xuc ((va dan) OR (va dao)) thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ban ky ((nang xa) or (nang ma)) hoi. lieu va cac xuc ((va dan) OR (va dao)) thai cua tre*.
